Table 2 Reisolation of Leptospira from blood.

A pig was considered infected if at least once a positive blood isolation was found. n.a. = not applicable

From: Erratum to: A novel octavalent combined Erysipelas, Parvo and Leptospira vaccine provides (cross) protection against infection following challenge of pigs with 9 different Leptospira interrogans serovars
